DEVICE .TO FACILITATE THBEAZDING SHUTTLES.

Specification. of Letters Patent.

Patented Aug. 45;, 1914.

Application filed January 30, 1914.: Serial No. 815,459.

To all whom it may concern Be it known that I, JOHN Djnirrs'rea To effect this I provide the shuttle with an.

appliance of sheet metal or other material, having an inlet and outlet eye for the thread the outlet eye taking the place of the usual pot eye of the shuttle and the appliance is so disposed and shaped. as to render the task of threading the weft into these two eyes, very easy;

In the accompanying drawings, which clearly illustrate the invention: Figure 1 is a plan view ofpart of a weavers shuttle with the appliance in positionand threaded. Fig. 2 is a side View thereof. Fig. 3 is a perspective view of the appliance. Fig, at is a sectional plan thereof. Fig. 5 is a side elevation of a slightly modified shape of the appliance, and, Fig. 6 is a plan of Fig. 5.

The appliance, which. renders it possible to easily thread the shuttle by hand, is made preferably of sheet metal, shaped to the contour as hereinafter described, and bent or formed with a flat roof (1. an inner wall 2) and an outer wall 0. The inner wall has an eye 6 formed therein with a slit .5 in the wall leading from the edge of the wall to the eye. The outer wall 0 is also provided withan eye 0 with its center co-incident to that of the eye b, and a slot 0 leads from the bottom of the wall 0 to the eye 0.

The appliance is secured to the shuttle cl withthe roof a fitting in a shallow recess to lie flush with the top of the shuttle cl, the inner wall I) lying pendant in a slot d formed in the shuttle, which slot is formed to coincide with the center, line of the shut tle or thercabout. The outer wall 0 lies flush with the side of the shuttle. The thread 6 can be easily drawnby hand into the slot (1, along with the outer side of the wall I) the edge of the wall I) projecting slightly beyond the slot to serve as a guide for the yarn into the slot. By pullingdownward on the thread it is guided by the curved edge fot the wall 6 until it passes up the slot b into the eye 6'. The threadis further pulled along the oblique edge 9 of the roof a and outer wall 0 until it can be passed up through the slot 0 to the eye 0, which completes the threading of the shuttle.

The appliance is secured to the shuttle by screws h or in any convenient manner, and at the part ofthe applianceinearest the tip 11 of the shuttle the wood is cut away suiiiciently, say up to the dotted line I;

at the top and the side to allow of the passage of the thread beneath the appliance and also for free playfor the thread beneath the appliance. The top of the shuttle may have a pin or small post m to guide the thread as shown inFig. 1.

Figs. 5 and (Sshow a threadingappliance in all respects similar to thatdescribed save that the slot (2 leading to the hole 0 isdiS- posed. more obliquely to prevent any tendency of the thread from falhngout. I declare that what I claim is: a

1. A. threading device for shuttles comprising a transverse connecting portion having two side portions depending therefrom, each side portion being provided with an eye and with a slot communicating with the eye and. extending to one of the edgesof r the side portion.

2. A threading device for shuttles c0mprising a transverse connecting portion having two side portions depending therefrom, each side portion being provided with an eye and with a slot communicating with the eye and extending to one of the edges of the side portion, said eyes being coincident withone another.

3. A threading device for shuttles comprisinga transverse connecting portion having two side portions depending therefrom,

each side portion being providedwith an eye and with a slot communicating With the eye and extending to one of the edges of the side portion, the forward edge of one of said side portions being convexly curved.

4. A threading device for shuttles comprising a transverse connecting portion having two side portions depending therefrom, each side portion being provided with an eye and with a slot communicating with the eye and extending to one of the edges of the side portion, the forward edge of said com nected portion being convexly curved,

5. A threading device for shuttles com prising a transverse connecting ,portionhaving two side portions depending therefrom, each side portion bcingprovided with an eyeand with a slot communicating with the eye and extending to one ofthe edges of the side portion, the. forward edges of one v of said side portions and ofsaid connecting tial lyl.coincidentwith. itslongitudinal axis] in which one .ofv saidside portions extend, said shuttle be ng-prov ded with recesses 1111;
